The issue here isn’t that Catholic’s can’t/shouldn’t be doctors. The issue here is that in this case you’d have to exercise your rights at the expense of others’ rights. For example, if you are a doctor, your job is to listen to the patient and provide medical information. You cannot impose your religious beliefs on others. This means that you cannot deny someone medical treatment just because your own religion disapproves.
Likewise, it is difficult for a Catholic doctor to prescribe something that is against Catholic beliefs. But the patient might not be Catholic, and you can’t force them to be by refusing to treat them, or judging them for not being Catholic like you are. But as a Catholic it’s difficult to do **anything **that is in contrast to what you are taught is religiously right. Other people’s religions may be different. And then your patient won’t be getting all of their options, because as a Catholic there are certain treatments you just won’t approve. If we support the Catholic doctor, then the patient does not get all of their treatment options. Likewise, if we support the patient, the Catholic doctor has to draw up treatment plans or prescribe meds that the doctor is religiously opposed to.
Definitely a lose-lose situation. You can’t support one’s rights without putting the other at a disadvantage. To ensure that you are getting information on all your options, you could ask for a doctor who isn’t Catholic, but what a waste of a brilliant mind just because a patient is afraid they might get a Catholic doctor who won’t approve. If I was a doctor, I would use my medical knowledge during the workday and then just pray that the patient chooses to do whatever is right. But as a doctor I would have no right to tell the patient, ‘look, this is a sin so I won’t let you do that even though it would solve your medical problem.’ I would give a patient all of his/her options and then just go home and pray that whatever decisions they make, that they make their peace with God about it. By prescribing birth control, for example, you are not forcing someone or telling someone to take it, you’re just giving someone all of their medical options. I know what is right and wrong in my own life personally, but I wholeheartedly support other people’s rights to make their own choices and decisions based on what is going on in their own lives. As long as they have made their peace with God about it, I wouldn’t feel bad about prescribing something that will help them medically.
